Nervous System & Endocrine System

Nervous System: Sending messages fast but they don’t last long

–Like an energy drink that gives you a quick burst of energy that doesn’t last very long.

Endocrine System: Sending messages slowly but they last a long time

– Like eating well, exercising and getting enough sleep will give you energy all day!

The Nervous System:Sends messages quickly but they don’t last long.

Broken into two parts:

• Central Nervous System (CNS)– Brain and spinal cord

• Peripheral Nervous System (PNS)– Carries messages to and from CNS

Central nervous system

Peripheral nervous system

The Nervous System: It breaks down into two parts.

Sympathetic and parasympathetic divisions of the nervous system

Summary of autonomic differences

Autonomic nervous system controls physiological arousal

Sympatheticdivision (arousing)

Parasympatheticdivision (calming)

Pupils dilate EYES Pupils contract

Decreases SALIVATION Increases

Perspires SKIN Dries

Increases RESPERATION Decreases

Accelerates HEART Slows

Inhibits DIGESTION Activates

Secrete stresshormones

ADRENALGLANDS

Decrease secretionof stress hormones

Endocrine SystemUses hormones that travel through the bloodstream. Takes

longer to get there but lasts a long time

The ReflexWorks by bypassing the brain so you can react quicker.
